Delta Air Lines has pledged to introduce free Wi-Fi on international aircraft from the end of 2024.
The airline is making fast internet access available on some US domestic flights from February 1 in partnership with T-Mobile.
It claims to be the first major US airline to offer free Wi-Fi as a “core element” of its customer experience.
The service will be offered on more than 700 aircraft by the end of 2023.
Delta also plans to bring free Wi-Fi on international and regional aircraft by the end of 2024.
Passengers must log in using their Delta SkyMiles loyalty scheme account or join SkyMiles on the ground or in the air for free to connect.
Chief executive Ed Bastian said: “At work, at home and everywhere in between, connectivity is essential to daily life, and your journey on Delta should be no different.
“Our vision has long been to deliver an experience at 30,000 feet that feels similar to what our customers have available on the ground.
“We didn’t just want free Wi-Fi to offer base-level service – we wanted it to be transformative for the entire onboard experience.
“It is imperative all customers onboard can enjoy their favourite content just as they would at home, and we’ve put this system through meticulous tests to make that possible.”
T-Mobile chief executive Mike Sievert added: “T-Mobile customers already get free in-flight Wi-Fi and now we’re partnering with Delta to bring that experience to all customers – regardless of their wireless provider – so that anyone flying Delta can enjoy online access from take-off to touchdown.”
